Reverse DNS Updates
Alright, y'all, Let's try this again.
I attempted this a year ago which led to much frustration and gnashing of teeth, but I'd like to try again because RFC 2317 has been the current best practice for over two decades, and RFC 3596 was written some 5 years later and has been an Internet standard since 2017 and there really isn't any good reason why a network provider won't do this trivial thing for customers who are paying extra for static IP addresses. It involves NS and CNAME records for IPv4 and NS records for IPv6 rather than PTR records, but a resource record is a resource record as far as the DNS servers are concerned.
I would like to have my RFC 2317 IPv4 reverse delegation working again for my /29 (something that was working between 2013 and 2019) and have reverse DNS pointing to my servers for my IPv6 subnet as well.
If, for whatever reason, Comcast refuses to do that, then I need the existing PTR records to be updated, including records added for a handful of addresses in the ip6.arpa zone.
Let me know what y'all need from me, and hopefully this won't be too stressful or frustrating for anyone involved.
